To a whom it may concern.-

Be it known that I, HEINRIGHTHIEMANN, a subject of the Duke of Anhalt, residing at 17 Kirchplatz, Stolp, Pomerania, in the Kingdorn of Prussia and Em ire of Germany, have invented anew an useful Improved Process of Utilizing Waste Amber, of which the following is a specification.

My invention relates to an improved. process of utilizingwaste amber;

A substitute for amber has already been made by preliminarily treating waste amber with solvents, then pressing the same while applying heat, and adding it to natural am ber or also to copals. The product obtained in this manner, however, owing to the imurities contained in the waste, was suitable only for the manufacture of inferior pro ducts, mostly dark amber-varnish.

The rocess forming the subject of my said invention is designed to so improve inferior brittle amber and waste amber or other such as copal, which are not by themselves suitable as a substitute for amber that they will form a substitute for valuable and expensive amber. ,-For this purpose- I employ instead of the crude waste amber the ingredients of the same which are soluble in chloroform, (01 and [3 resin.) 1

- On treatment of the crude waste in the well-known manner with chloroform the soft 02 and [J resins are obtained free from imurities. This mixture of 'a /3 resin is added to the brittle sorts of amber or also to other resins, especially copal, which thereby have such a density, strength, and pliancy imp arted to them that they may replace amber of good quality, but, are considerably cheaper than the latter.

The .compound obtained by my process is designed to be molded to form articles of various kinds, such as cigar-holders, ornaments, and the like. i

In carrying this process into practice I pulverize waste amber and repeatedly sub purpose of so lmproving the same that they ject the same to the action of warm chloroform a substitute for expensive amber. form or also ether. The solution obtained 2. Aprooess of utilizing waste amber, conin this manner is subjected to distillation, sisting in intimately mixing the mixture of thereby producing a yellowish-white mixture of resin, the a [d resin of amber. By heating this mixture it is freed from the last traces of the solvent, andafter allowing the not only. an increased strength, but also a more natural appearance, the product exhibiting a milky and cloudy appearance peculiar to natural amber.

-As a rule I add from ten to thirty grams of succinic acid to one k logram of a fl resindust.

-For improving copal grams ofthe mixture of a [3 resin-dust and succinic acid with one thousand grams of pulverized copal to form a fine dust, this dust being introduced into the heating-chambers of a hydraulic press'and compressed under great pressure after heating. During the ressing of the heated mixture an irregular distribution of the acid within the mixture takes place, which gives the product a striped cloudy appearance. After the cooling a homogeneous product is-obtained which may be worked like wood, horn, amber, and other similar natural products and is particularly adapted for the manufacture of ambroid.

. In case brittle amber is to be improved use for one thousand grams of amber-dust from ten to fifty grams of the mixture of a resin-dust and succinic acid, according to the hardness of the amber, less being added to softer amber and more to harder amber.

The purified mixture of a' [J' resin is very well suited for the preparation of the valuable light amber-varnish, while the 3/ resin purified by fusion gives a considerably harder varnish than may otherwise be obtained di rectly from amber.

To seventy-five parts of amber resin I add fifty-five eighty parts of turpentineoil.

I What I claim as my invention, to secure by Letters Patent, is

1. A process of utilizing waste amber, consisting in intimately mixing the mixture of a and [5 resin obtained in the known manner from waste amber with succinic acid, and

and desire ner from waste amber with succinic acid, and adding this mixture to cop al, for the purpose of so improving the same that it forms a substitute for expensive amber.

3. A process of utilizing waste amber, con- -dust thus produced I sisting in extracting a and [3 resin by means To the pure 0: [5 resin add succinic acid. By this means I achieve I work twenty-five parts of linseed-oil varnish and adding this mixture to other'resins, for the 0: and [3 resin obtained in the known manv of a solvent, evaporating thesolvent','allow- In testimony whereof I have signed in ing said resin to harden, powdering the same name to this specification in the presence of IO and mixing with succinic acid. two subscribing witnesses.
